Specification of Letters Patent.

Patented May 15, 1917.

Application filed January 12, 1916. Serial No. 71,771.

To all whom t may concern:

Be it known that I, WILLIAM F. AL- BREci-rr, a citizen of the UnitedStates, residing at Salt Lake City, in the county of Salt Lake and Stateof Utah, have invented new anduseful Improvements in Faucets, of whichthe following is a specification.

This invention relates to improvements in faucets, and broadly stated,has for its object the provision of a device of this characterconstructed whereby the flow of water can be readily7 and easilytemporarily cut off when desired by an auxiliary valve constituting apart of the main valve, to permit the valve and stem to be removed forrepairs, or when the occasion may demand.

Specifically stated the invention provides a device of this characterembodying among other features a hollow valve stem having normallypositioned in the lower end thereof, an element constituting anauxiliary valve adapted to be transferred into the inlet passage totemporarily cut off the iiow of water, when it is desired to remove thevalve and stem for any purpose whatsoever.

Another object of importance resides in the provision of a constructionof a device of this character, wherein both the stem of the main valveand the stem of the aux iliary valve can be simultaneously controlled.

The nature and advantages of the invention will be better understoodfrom the following description, when taken in connection with theaccompanying drawing, the specific construction, combination andarrangement of parts being fully described, illustrated, and clearlydefined in the appended claims.

In the drawing forming 'part of this application like numerals ofreference indicate similar parts in the several views and wherein:`

Figure 1 is a longitudinal sectional view through the faucet showingvthe parts in normal position;

Fig. 2 is a similar view showing the manner of transferring theauxiliary valve into operative association with the inlet passage.

Fig. 3 is a perspective view of the auxiliary valve.

Referring more particularly to the drawing A indicates generally thefaucet which may be of any suitable construction to permit of its usewhere an ordinary faucetmay be employed. rllhc invention, however,embodies in this specific instance a casing 5 having an inlet Gdepending therefrom, and a laterally extending outlet 7, while risingfrom the casing is an extension S disposed in axial alinement with theinlet 6, and wherein is arranged the valve stem 9, the extension beingclosed by means of a cap as shown. The casing is formed to provide avalve seat 11 at the juncture of the inlet 6 with the outlet 7, and uponwhich seat the valve plug 12 on the lower end of the stem 10 is adaptedto normally engage, the valve plug being exteriorly threaded toaccommodate the threads on the interior of the extension 8, whereby thevalve plug is moved toward and away from its seat upon rotation of thestem as will be readily understood. The lower end of the plug 12 isrecessed as at 13 for the reception of a rubber gasket, or otherIsuitable packing 14 to provide a fluid tight joint between the partswhen the valve is in normal position.

Now with a View of temporarily cutting off the flow of water, when it isdesired to remove the valve and stem for the purposeof repairs,especially when it is desired to substitute a new packing for an old andworn out one, I employ an auxiliary valve plug 15 which is exteriorlythreaded and normally screwed within a bore in the main valve plug 12,which bore communicates with the recess 13 as shown, the plug 1hmanifestly constituting a part of the main valve when in this position.The plug 15 is provided with a transverse groove 1S at each end for thereception of a screw driver, or other suitable tool to manipulate theplug in the manner to be presently described, however, one of thesegrooves is provided to facilitate the initial association of the plug 15with the main valve 12. As above stated this is the normal position ofthe auxiliary valve 15, but when it is desired to temporarily cut Offthe flow of water through the faucet, the 'screw 16 which holds thehandle 17 positioned upon the stem is removed, and the screw driverinserted within the stem into engagement with the transverse groove ofthe plug 15. The` screw driver is then rotated to transfer the plug 15from the main valve 12 into the exteriorly screw threaded passage of theinlet 6, this passage being reduced at its upper end to a size to snuglyreceive the plug 15 so as to provide a fluid tight joint when the latteris positioned within the inlet opening. Subsequent to this positioningof the plug 15, the cap 10 may be removed from the extension 8, and thestem together with the main valve 12 yrotated in a direction opposite tothe rotation of the plug 15 for the purpose of removing the stem fromthe casing 5 for any purpose whatsoever. In returning the parts tonormal position the stem and main valve 12 are first positioned` Withinthe casing 5 so that the valve 12 will engage the seat 11. The screwdriver is then inserted Within the stem into engagement with the plug15, and the latter rotated in an opposite direction to its initialrotation, whereby the plug is screwed Within the bore 13 of the mainvalve 12, thereby rendering the faucet again ready for use. The washeror packing 14 is interiorly threaded to engage the threads on the plug15, the latter materially assisting to prevent the washer from turningsubsequent to being placed in position, although the washer can be heldrigid in any other suitable manner.

It is believed that from the foregoing description the nature andadvantages of the invention will be thoroughly understood withoutrequiring a more extended explanation. However I desire to have itunderstood that I do not limit myself to the precise construction andarrangement of parts herein shown and described, as the same is merelyillustrative of certain embodiments of the'invention, and that variouschanges may be resorted to when desired as fall within the scope of theappended claims.

What is claimed is A faucet comprising a casing having an inlet andoutlet,va valve seat formed at the juncture of said inlet and outlet,the inlet immediately in advance of the valve seat being screw threaded,a hollow extension rising from said casing in axial alinement with saidinlet, a hollow valve stem arranged within said extension forreciprocatory movement, a main valve plug on the lower end thereofhaving an interiorly threaded bore communicating with the interior ofthe valve-stem, an auxiliary valve plug threadedly secured within saidbore and forming part of the valve, and said auxiliary plug having Aatransversely disposed groove at each end thereof to accommodate asuitable tool for transferring said plug from the main valve intothreaded engagement with said inlet to temporarily cut od the flow ofwater for the purpose described..

In testimony whereof I affix my signature in presence' of two witnesses.
